anyone know how to deinterlace DV source?

[Stinky]

I'm working with DV source and I want to create an SVCD from it but the source is interlaced - I found a few bits that said you can do it with TMPGEnc but I can't find any detailed information on the settings (there are a lot of deinterlace options in TMPGEnc)

Is TMPGEnc the way to go? Would DVD2AVI work better? Can you feed DV source into DVD2SVCD?

thanks in advance

Since SVCD supports interlaced video you shouldn't have to deinterlace at all! Deinterlacing is only required when you are going from an interlaced source (e.g. Video Camera, TV broadcast) to a video format which does not support interlaced video (e.g. VCD)

But if you want to deinterlace anyway, Virtualdub has a good deinterlacing filter

Yea I found a few pages with VirtualDub filters but I'm not sure how to get the DV into VirutalDub.

I'm guessing DVD2AVI project file - converted to VFAPI then put into VirtualDub then frameserved into TMPGEnc .... but I haven't tried it yet.

Dave B: I didn't think I had to deinterlace also but the resulting SVCD files are full of interlaced lines during fast motion - I'm not sure why that is exactly but I can't get rid of it.

To get DV into most programs (TMPGEnc, VirtualDub, etc.), you'll need a DV codec other than the MS one. I use the MainConcept DV codec (http://www.mainconcept.com/archive/mcdv204.exe). It is a demo, but decode is free (encode puts a logo in the upper left). Full version is $50.

Once this is installed, you can either go directly to TMPGEnc or go through VirtualDub for processing and then frameserve to TMPGEnc.

Stinky,

It's good to see that you get lots of interlace lines during fast motion! That is exactly what should happen...if you are watching on you computer.

Burn it and watch it on TV, it will look much better, and those lines are now bits of motion that you would otherwise have lost or blurred!

(ie the two (interlaced) halves of the frame are displayed 1/50th or 1/60th of a second apart...to give you much smoother motion than 25 or 30 fps can give..and an effective resolution increase due to the 1 line vertical offset)

On my TV with interlaced SVCD I can clearly see the same lines as in the DV source.So I always deinterlace my avi before converting tp SVCD.Yes, a little more blurry, but much better then clouds or fire (at explosions) with visible lines.

If you are seeing interlace lines on TV (when using interlaced SVCD) , I can only suggest that:

a) you have the field order wrong
b) the encoder you used did not handle interlaced signal properly (either in it's input or output settings)
c) you have done some area based filtering on a frame basis (eg smoothing/sharpening etc). This would cause information from one filed to be blended into another and give the apperence of 'interlace lines'

coz it should work.

I'm using always ULEAD MF for encoding and always setting frame-order to full-frame.Normally this works, but with some movies (Back to the future III) it was so bad, I hab to deinterlace the video with V-Dub before converting to SVCD.I'm caopturing thru DV Bridge from VHS-tape, maybe that caused the trouble.
After deinlacing with V-Dub, the movie is perfect.
